    • Removable valve core
    • Item #QTB0005

    Great.

    • Familiarity: I've used it once or twice and have initial impressions

    Bought these for spare flat fixes and thankfully, they've sat idle in the saddle bag. I'll report back if I ever have to get around to using them.

    Removable Valve Cores

    • Familiarity: I've put it through the wringer

    I buy these tubes specifically for the removable valve core. That way you can fill with your sealant of choice and avoid all the goat heads.

    Industry Standard

    • Familiarity: I've put it through the wringer

    The only thing worse than having to buy tubes in 2018 is buying tubes that aren't 'Q' tubes, just don't do it! With soo many road tires going bigger and bigger and grinding gravel on eveyone's mind, it is time to make sure your old spare is up to the task of keeping you out riding and not just a band-aid to get you home.

    When you can't ride tubeless, you might as well run a 'Q' tube!

    Who uses these things?

    • Familiarity: I've put it through the wringer

    It's a tube. Let's get that straight.
    This is about as "normal" as tubes get. It's not a lightweight option, but that's ok. What it does have that will keep me coming back is a removable core. 'Nuff said.

    It's a tube

    • Familiarity: I've put it through the wringer

    It really does what all else tubes do which is hold air so you can ride your bike. May not be as light as other tubes but guess what? All tubes eventually get holes in them. Great thing about Q tubes is they do have removable valve cores which is an extra bonus

    Basic tube... it works

    • Familiarity: I've put it through the wringer

    Use these tubes on a set of cross wheels for my boys bike, and they work out great. Nothing crazy or unique, but they do the job that is required of them.

    Holds Air

    • Familiarity: I've put it through the wringer

    These tubes do what they are supposed to, hold air. Medium weight so no to heavy but not super light. It is also nice that they have removable valve cores to make adding a little sealant a breeze.

    Unanswered Question

    Do these have a removable valve stem? The picture seems to suggest they do, but there's nothing in the description about it.

    can these tubes work with a 700 c x 32 mm...

    can these tubes work with a 700 c x 32 mm tire? The description says they are just for 700c x 30mm but usually there is a bit of a range to what sort of tire a tube can go in.

    chrp604757,



    I am using these tubes in 32's currently without any issues. The manufacturer lists the sizing from 28-32mm, but I think you would probably be safe using them in tires slightly beyond a 32.

    What size range of tires do these tubes...

    What size range of tires do these tubes fit?
